摘要
目的:观察“高住低练”对运动机体体液免疫能力的影响。方法:16名男性运动员随机分为2组,“高住低练”组每晚在模拟3000m海拔高度(氧浓度为14.2%)的低氧舱内休息,“低住低练”组在常氧环境中休息。两组在常氧下执行统一的训练计划,共4周。采用散射比浊法分别测定实验前、第1天、2周、3周和4周后血清补体3、4(C3、C4)的含量。结果:“高住低练”组C3含量在第2周时明显升高(P<0.01),第3周和第4周也明显高于实验前水平(P<0.05),而C4含量在前2周有升高趋势,但无显著性差异(P>0.05),第3、4周呈持续降低变化。“低住低练”组C3、C4含量在4周训练期间基本维持在一个较稳定水平,没有显著性差异(P>0.05)。结论:模拟3000m海拔“高住低练”4周,运动员血清C4有升高趋势,C3明显持续性升高,提示“高住低练”方式对补体系统有一定程度的激活。
The purpose of this study was to observe the effects of "living high-training low" on humoral immunity of athletes. 16 subjects were randomly divided into two groups. Living high- training low group stayed at the hypoxic cabin (simulating altitude at sea level of 3000m, 14.2% O2) per night ,while the living low-training low group stayed at normoxia condition. Both of two groups used the same training plan at normoxia condition for four weeks. The contents of serum complement 3 and 4 (C3 ,C4) were measured per-experiment ,first day,second week ,third week and fourth week respectively. The result showed that the contents of C3 in living high-training low group increased remarkably at second week (P〈0. 01),while the contents are obviously higher than that of pre-experiment at second and third week (P〈0. 05). The contents of C4 tended to increase at first two weeks ,but no significant difference (P〉0. 05). At the third and fourth week,it continually decreased. The contents of C3 and C4 in living low-training low group maintained at a steady level during the four-week-training. There was no significant difference (P〉0. 05). It concluded that living high-training low of simulating altitude at sea level of 3000m for four weeks, the serum C4 tended to increase, while the C3 continually increased remarkably. It suggested that the model of living high-training low had certain activation on complement system.
